Frequent locations

[ISHOEJ]

Does any one know how frequent locations get registered. ???example i visited A and B locations every day but I can only see A location under frequent locations why i cant see B location ??? And how long it take time to register locations under frequent locations? ? I cleared my frequent locations history on 17 august 2015 and on 19 of august 2015 location A get registered under frequent locations. ..does any one know what is the time delay to register new location if i visited 2 same locations every day in my case location A and B ???

Don't think there's really any clear-cut algorithm that is (publicly) known.
